NFL Star Jason Taylor Is a Financial Disaster ... Says Ex-Money Man

EXCLUSIVE

7/18/12 -- Taylor's lawyer, Raymond Robin, tells TMZ, "The allegations of Mr. Taylor being a colossal financial failure are completely untrue. Mr. Taylor has been very successful in his business ventures.”

Robin adds, "The allegations in our original complaint speak for themselves. We have copies of the checks that Mr. Kim wrote directly to himself to verify our claims."

Ex-NFL superstar Jason Taylor is a colossal failure when it comes to handling his money ... so says Taylor's former money manager who's now suing the future Hall of Famer for $1,000,000.

Taylor -- who played in the league for 15 seasons -- is being sued by Eric Kim ... an investment broker who claims the two used to be great friends. In fact, Kim says they golfed together, played high-stakes poker together and Taylor even invited Kim to watch Jason compete in the "Dancing with the Stars" finale.

According to the lawsuit filed by Behren Law Firm, Taylor eventually "begged" Kim to step in and handle his financial situation ... "due to a history of colossal failures in his investments."

Kim says he obliged ... and Jason began to make some serious profits. Kim claims he advised Jason to cash out while he was ahead, but Jason didn't listen.

In return for all of his hard work, Kim says Jason turned on him and began trashing him all over town ... calling him a "thief" and telling people he "stole from me."

We broke the story, Taylor SUED Kim last year ... claiming the guy is a fraud who scammed him out of $275k. Kim denies any wrongdoing.

In fact, Kim says he's the real victim ... because Taylor never paid him a dime in commissions. Now he's demanding at least $15k for his services ... plus a MILLION BUCKS for the damage to his reputation.
